 Hi, everybody. I'm Jack Hanna. Since I was a boy growing up on a farm in Tennessee, I've been fascinated with animals. I'm not only in awe of their beauty and kindness, but also their tireless work ethic. Just look at the birds who gather supplies to build nests, or Swiss foxes who work hard to provide for their young, or penguins who travel up to 500 miles to secure food for their families, or bush babies whose impressive jump allows them to navigate the trees and the wild in search of fruit. This remarkable work ethic is shared by our best friends, the canines.
